I have three Big Hauler engines all from the 1990s one of the rear drive wheels on one engine is broken and trying to leave the chassis.  I would like to upgrade and replace the chassis on all three because I am sure the others will have the same problem soon. I don't Know the part numbers to order for replacement of the chassis.  The numbers on my boxes that the engines came in are 90016  90025  90026 .  Any help with the part numbers to order would be appreciated. I would like to replace the chassis my self, it doesn't look to hard to do.  thanks Bill

I am new to G scale and I want to convert my Bachman B&O Blue line engine made in 1997 to DCC.  What are your recommendations so that I can control the engine power, engine sound, and lights?  I think I can do the conversion but I don't know what is compatible with your Bachman engines. I have a PIKO 55040 DCC smart controller. Thanks Bill
